so that it may be positioned to reflect the light in a suita iledirection within the housing.

The back wall of the housing, below the portion receiving the socket lis provided with a suitable Ventilating structure indicated at 9, topermit the inlet ot cool air into the casing, in order to prevent theaccumulation ot heat therein trom the lamp bulb Y, the healed air beingexhausted through the ventilator structure 10, mounted in the cover 2,immediately above the lamp '7.

The end ot the cover, at the end oi' the housing opposite that to whichthe lamp is positioned is formed with a substantially large opening 11,and below which is suitably supported on the bottom tace otl the cover aclear glass plate 12, by suitable braclxets to form a frame -torreceiving negative and printing paper in such relation that the iilm maybe suitably printed on the print paper by eliminating the interior ofthe housing in a manner as will be hereinafter set forth. At the rearedge ot' the opening 11 is suitably hinged a bracket member 13, hingedlyconnected together at their adjacentedges, which are of a size adaptedto lit within the opening 11 and entirely close the same, so that 'whenthe negative and printing paper are properly arranged within the opening11, said bracket member will hold the same in contact with the glassplate and in proper position for printing. In the rear of the opening11, the cover 2 is formed to receive, on the upper tace thereof, a platemember 14 which is provided with T-slots 15, for receiving the headedprojections 16 on the bracket members 17, which pivotally mount a handlever 18, carrying resilient strip members 19, in position to engage thecentral portion ot the cover 13 when the said hand lever is moved towardthe cover 2. The provision of the headed projection 16 on the bracketmember 17 provides a removable connection between the cover and the handlever 18, so that when the device is to be carried about the base plate,the hand lever may be detachably and suitably stored within the housing.A spring pressed and manually operable latch 2O is mounted on the underside ot the forward end of the lever 18 for suitable cooperation withthe latch plate 21, mounted on the forward edge ot the cover in front orthe opening 11, so that the lever 18 may be retained in depressedposition toward the cover 2, in order to hold the backing sections 13 infirm engagement in the opening 11, with the negative and printing paperand for lholding the same firmly against the glass plate 12. A movablepartition wall 22 is mounted on the shaft 23,

which is rotatably mounted in suitable bearing members secured to thebottom wall 24, ot the casing 1, so that the partition wall is hingedlymounted on said bottom wall. i suitable coil spring 25 is mounted aroundthe central portion ot the shaft 23, with one end engaging the partitionwall 22 and the other end engaging the bottom of the housing 1, fornormally moving the partition wall in the direction of the arrow inFigure 2. so that the same will lie flat against the bottom 2st oi thehousing 1, under the nor* mal action of the spring 25. trame members 26are hingedly mounted on the Jfront and bacl: walls o'tthe casing orhousing 1, and carries transparent plates 27 o t suitable lightrestricting character, which are adaptedto be swung inwardly in opposedand aligned relation transversely of the housing, and which extends fromthe lbottom to the top portion thereof as is clearly illustrated inFigure 4l. rllhese iframes 2G and transparent plates 2l' are now .information and in the position shown in Figure 4iadapted to receive asuitable retaining member 28 having a pair of U- shaped clips 29 whichfit over the upper edges of the frame 26, and retain the frames ininwardly projecting relation as shown in Figure Ll in the housing. Inthis position, these plates form a stop to limit the movement ot' thepartition wall 22, so that the same will be held in a substantiallyvertical and transverse position within the housing 1. In this positionor the partition wall 22, the housing will be divided into a pair oicompartments, one o1 which will be lignted by the lamp 7 and the othercompartment being` substantially dark, through the light being cut offbythe partition 22. A small portionV of the light, however, will beadmitted to the other compartment around the edges of the partition 22,which terminates in spaced relation with the front and rear walls ot thehousing. rlhe light admitted to the second con'lpartment within thehousing when the partition wall is in a vertical transverse plane asjust described, will be controlled by the plates 2?, which are oi"suitably colore glass, 'for instance, yellow glass, to admit onlycertain rays from thc` lamp 'i' to illuminate the compartment at theopposite end of the housing.

A suitable cont-rolling means for theposition otl the partition wall isprovided, to control the position ot the partition wall in accordancewith the operation ot the lever 18. This mechanism includes an arm 30rigidly mounted on theV sha'rt 23, with which is connected the laterallyextending end 31 or' the rod member This rod member is suitably Vandslidably mounted in a holder which is pivotally mounted at 34, on thefront wall of the housing. The upper end ot the rod member S2 projects Apair of lll() weefsel above the holder 33 and receives a suitable head235, which is adaoted to be engaged by the head on the operating pin 35,mounted 'or limited sli ng movement in the @over -"iis pin-36 isr molinoiu the path 'ot rent oi.E the lever 1S, so to be eng by the stud mountedon the unr side ot the lever 18, when the same is inoed to depressedposition as illustrated in rieure 1i, with the latch 2O engaged with thel; -ch plate lfhenit-he partition wall `i a sulzstantially vert-'calposition, in its movement by the plates 2LT, i, l ot the pin 36 so thatwhen the negative is to he printed and the lever 18 depressed to holdthe backing sections within the opening 1l, the partition Wall, will beswung to an inclined position through the operation ot the rod Bila ythe pin 36, as illus-rated in Figur-e 2. In this position of thepartition Wall, as illustrated in Figure 2, the light f i f7 T 1 L! 4. iv ,1`IY, irom the lamp i pill oe ieueered upuaior,y thereby at theprooer angle for concentration upon the glass plate 12, sothat it willproperly print the negative on the printr paper positioned in theopening ll.. The light admitted past the partition -WallV 22 in thevertical position thereof through the plate 27 is only suiicient topermit the operator ot' the printer to properly position the negative inthe openingll, with the print paper in proper position thereon.

t the end ot the housing in which the lainp 7 is mounted, the front Wallis provided With a suitable openingBS, and over said opening lon therear face of the iront Wall is mounted a suitable semi-transparent platestructure 39, adapted to permit the light :trom the lamp 7 to shineoutwardly through the plate structure so as to provide the propercharacter of light as used in a dark room, and ordinarily referred to asa ruby light. A suitable door d() is hinged along one edge of thisopening 3S and forms a closure therefor when the light from the `platestructure 39 is not desired.

rllhe end ot' the housing 1, adjacent the lamp 7 is formed with anopening 41 closed hy a suitable hinged jaw d2, and over the bach oit'which is suitably mounted on the inside tace ot' the end Wall, a groundglass plate Llf3, to iorm a light diffusing member. Referringparticularly to Figure 6, a traine 44 may be removably positioned in theopening ell, for holding the negative, so that enlargements maT be madewith a suitable lenlarging apparatus oi' any desired structuralcharacter, as indicated by the numeral A45. 'lfhe ground glass plate, inthis connection, serves as a light diffusing medium, so as to properlydistribute the light from the lamp 'L over the surface or" the negativeheld inthe frame 44;. The plate'li may also serve in connection with aphotographic attachvfill be in the path of movementmentapplied to theend of the case or housing, so that a suitableview. to be photograohedmay beioeused upoi'i the plate 43, but iirsueh a. mannerv that theactual toons oi' the image will' occur in the plane t the negativeplacedfin the frame L -l, so that in the subsequent positioningfo't thenegative plate .vithiirthe frame dit, after the focusing the image, thepieture can be taken on the negative plate iii-,the usual and Well knownmanner, the light 7 being extinguished'duringthe:taking o1". pictures asde-l scribed;

lThis construe-tion is adapted to have the disassembled so that thelever 18, the lamp soelret l and other parts oill the photographieapparatus such as the pap-er, negative and other-developing apparatusmay all be stored Within the housing 1, When the same is notusedy inorder thatit n'iay be eonveniently carried'about from one place*Jo-another, For this purpose, the clip memv ber QS is removed 'from thetrame 26 to permit the same to swing against the front and rear, Wallsof the housing respectively, so the i partition,` Wall 22 may be movedon its pivot under the influence ot the spring 25, so as to restagainstthe bottom thereoi'; In this position of the parts, therods 32will` assuuie the position illustrated in Figure 5 4of the drawings, sothat the cover 2 may be applied and suitably locked to close theopen endofthe housing' and the pin 3G Will be out ot alignment With the head 35,sonas notto operate the movable partition 22 inthe manner as heretoforedescribed, as shown in Figure 2,

lt will thus be seenthat a highly practical and. novel'photographicprinter has been produced, which is capable of efficiently printingphotographs as Well as serving a number of additional purposes.
